  • the female terminals such as the contact piece 30 and the beat piece 31 may be made of a conductive base material made of a high-strength, high-cost copper alloy such as Be copper or titanium copper, but these copper alloys are expensive. Therefore, lower cost Cu—Ni—Si (Corson) alloy, Cu—Ni—Sn—P alloy (for example, copper alloys such as NB109 and NB105 manufactured by DOWA Metaltech Co., Ltd.), phosphor bronze, etc. Usable and preferred.
  • a male terminal such as the male tab 11 is preferably brass.
  • the protrusion 40 can be formed by press working using a mold, for example.
  • a part of the press die of the female terminal may be changed.
  • the timing for performing the press work may be before or after the plating process.
  • the processing method is not limited to press working, for example, a protruding portion is formed by Sn plating.
  • the shape of the protruding portion 40 of the female terminal needs to be changed, and the male terminal may be the same as before.
  • the beat part 41 can provide the protrusion part 40 easily by press work.
  • the protrusion part 40 showed the example which has both the advancing direction side top part 45 which protrudes in the advancing direction X1, and the reverse direction side top part 46 which protrudes in the reverse direction X2 in the above embodiment, it is a male type
  • the projecting portion 40 has a traveling direction side top portion 45 projecting in the traveling direction X1 and a reverse direction projecting in the reverse direction X2. It is sufficient that only the side top portion 46 and the crossing side top portion 47 are provided, and the traveling direction side top portion 45 may be omitted.
  • FIGS. 7 and 8 an example of a plane on which the side wall portion 43 provided around the contact portion 42 is inclined is shown.
  • the side wall portion 43 has a curved surface that protrudes outward, or As shown in FIG. 19, the side wall portion 43 may be a curved surface convex inward.
  • the side wall part 43 may be a vertical plane.
  • FIGS. 16 and 17 an example of a plane on which the side wall portion 43 provided around the contact portion 42 is inclined is shown.
  • the side wall portion 43 has an outwardly convex curved surface, or As shown in FIG. 22, the side wall portion 43 may be a curved surface convex inward.
  • the side wall portion 43 may be a vertical plane.
